if they have no obvious common factors (such as 3!!!!!!!) then you multiply them to get the GCF.

60, 72, 84, 90 and 96 each have twelve factors.
0.8
1250
Three
60,120,180 and multiples of 60
1
Twelve
Since 12 is a factor or 36, it is automatically the GCF.
The Least Common Multiple (LCM) for 12 15 is 60

1,2,4,7,9
The answer is 4.
2
The greatest common factor between twelve and eight is four. Don't get confused about greatest common factor and greatest common multiple. There is GCF and GCM, be sure to pay extra attention to the last letter or word, whichevere form it is in.
12.5
The GCF is 3.
